IMPRovEMENT IN lRAllvJoAlwoArz HEATERs.

Specification forming part of Letters Patent No. 148,440, dated March 10, 1874; application tiled February 19, 1874.

To all whom it may concern:

Be it known that I, WILLARD M. FULLER, of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Railroad- Car Heaters; and I do hereby declare that the following is a full, clear, and exact description thereof that will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings and to the letters of reference marked thereon, which form a part of this specification. l

The nature of my invention consists in the construction and arrangement of a railroadcar heater, as will be hereinafter more fully set forth.

In the accompanying drawing, Figure l is a plan view of my car-heater. Fig. 2 is a longitudinalvertical section of the same through the line x Fig. l; and Fig. 3 is a transverse verticalA section through the line y y, Fig. 2.

A represents a boiler of any suitable dimensions, provided in its bottom with a number of descending vertical tubes, B B,whieh are closed at their lower ends, and increase the heating or steam-generating surface materially. C represents the iire-boX arranged be. low and in front of the front end of the boiler A, and the walls of which extend upward at the front end of the boiler above the same, forming a magazine, D. E is the flue under the boiler leading from the fire-box C to the chimney G at the rear end of the boiler. a is the grate in the tire-box, with ash-pit H underneath. I is a draft-flue, extending in front of the magazinev and re-box down to the ash-pit H; and said flue is at its bottom,on the side, provided with a door, I), as shown in Fig. 2.

'The heater, thus constructed, is located entirely under or below the floor W of the car, a place being cut out in the floor for the heater, and said space covered by a suitable grating, J, which has an aperture for the passage of the chimney G, and another aperture through which the cover K is placed on top of the magazine D. The re being made on the grate a in the tire-box C, air is supplied to the iire downward through the 'grating J bottom of the interior ofthe car, also answers another very important purpose. It is well known that in a closed room or car, where many persons are breathing, the air soon be comes so impregnated with carbon as to be unt for respiration, and that this impure air being heavier than pure air will settle down to the bottom ofthe car. By now taking the air from the interior of the car at the bottom to supply the hre, this impure air is drawn off, thus establishing perfect ventilation. The downward draft through the flue I is ordinarily sufficient to keep the fire going; but if more air should be required, especially when tirststarting the re, the door b may be raised, more or less, by means of a rod, e, when air will rush in directly to the ash-pit and fire. After the tire is started, the magazine `D may be filled to the top, and as the fire will not go above the top of the iiue E it forms a perfect self-feeder. The cover K over the magazine D being closed when the magazine is filled with fuel, the draft from the iiue I passes up through the grate a and under the boiler to the chimney G. Thus the magazine acts as the ordinary feeder in the self-feeding stove, in this instance the novelty consisting in the relation of the devices to the ear-floor IV, in order that the attendant may attend to and regulate the device from the inside of the car, at the same time having the boiler and re belowr the car-floor out of the way, and allowing the water to return by its own gravity to the boiler, and also furnishing a means of ventilation to the car. At the end of the flue E is a door, h, for purposes of cleaning out the flue and chimney. The grate a is vprovided with a suitable shaker-rod, d.

This heater is intended to heat the car by steam, on the same principle as described in the Letters Patent Nos. 144,527 land 145,167, heretofore granted to me; and, as the boiler is located below the bottom W of the ear, the

return of the water of condensation is greatly 2. -The magazine D, provided with cover K, facilitated. The ear is also heated by radiain combination with the ue I and boiler A,

tion from the boiler through the grating J. arranged below the ear-floor W, as and for the Having thus fully described my invention, purpose herein set forth. what I elaiin as new, and desire to Seenre by In testimony that I elailn the foregoing,r I Letters Patent, is have hereunto set my hand.
